is there a way to globally override the materials on a cosmos asset? i need this truck model (attachement) to be white. do i need to override each material 25+ times? (would be easy if we had access to geometry level as we could use the hypershader)
Hi!
Yes, there is 
In V-Ray 7 or newer there is an option called Force default shader
You can assign a material to the overall proxy and when you enable the option it will assign that material to the whole object.
Does that solution work for you?
perfect, exactly what i needed thank you. i would have never guessed that this would be the thing i needed to tick on. i would have expected something like a drag and drop field to drag the material onto it.
